The paper considers the use of nanomaterials, in particular nanoplastics, in manufacturing heat radiators for powerfull SMD-LED. Modern LEDs could not operate without effective system of heat dissipation due to their high power and widespread transition to new small-sized SMD package. At the same time widespread LED lighting sharply raised the question of reducing the cost of cooling systems for commercial fixtures. The use of traditional cooling systems with radiators from metals and their alloys has meant that the radiators have come to occupy a significant portion of the cost of the LED lamp. Not only metals are expensive by themselves, but technology for manufacturing metal radiators is complicated and expensive. Modern nano-plastics although inferior in thermal conductivity for metals, but they are much cheaper, both in composition and in technology of manufacturing radiators. So it gives serious competitive advantages for new materials, especially for the cooling systems of commercial electronic devices. New materials based on plastics with nanofillers are able to compete successfully with metal radiators with respect to the relation price-quality.
